Dilute solution: kind of solution that contains a small amount of solute in proportion to solvent
Saturated solution: A solution that contains all the solute that can be dissolved in the solvent under a given temperature and pressure.
Unsaturated solution: a solution that contains less than the maximum amount of solute that can be dissolved in the solvent.
Supersaturated solution: a solution that contains more dissolved solute than it normally can contain under a given temperature and pressure.
suspension: a substance that does not dissolve in another substance but uniformly mixes with it then separates upon standing.
Dehydration: water of crystallization that is driven off by heating
Anhydrous form: Form of the substance left after dehydration.
efflorescence: process by which some crystals lose their water of crystallization.
distillation: process by which a solvent can be separated from a solution or mixture
distillate: condensed vapor
hygroscopic substance: substance that absorbs moisture from the air.
deliquescence: process of dissolving in absorbed moisture.
Metallurgy: science of extracting metals from their ores.
metalloids: elements that have characteristics of both metals and non metals
acid: a substance that contains hydrogen that may be replaced by a metal.
Bases: substances that are combinations of oxides of metals with water.
alkalies: other name for strong bases
ions: atoms that carry an electric charge
electrolytes: substances that conduct electricity when dissolved
electrolysis: chemical change caused by conducting a current through an electrolyte.
electroplating: A process in which a metal is separated and deposited on an electrode surface.
PH scale: scale of values indicating acidity or alkalinity of a substance
Indicator paper: paper impregnated with a chemical that changes color in the presence of acids and bases.
